TLDR
It is found that the SPIN protocols can deliver 60% more data for a given amount of energy than conventional approaches, and that, in terms of dissemination rate and energy usage, the SPlN protocols perform close to the theoretical optimum.Abstract:
In this paper, we present a family of adaptive protocols, called SPIN (Sensor Protocols for Information via Negotiation), that efficiently disseminates information among sensors in an energy-constrained wireless sensor network. Nodes running a SPIN communication protocol name their data using high-level data descriptors, called meta-data. They use meta-data negotiations to eliminate the transmission of redundant data throughout the network. In addition, SPIN nodes can base their communication decisions both upon application-specific knowledge of the data and upon knowledge of the resources that are available to them. This allows the sensors to efficiently distribute data given a limited energy supply. We simulate and analyze the performance of two specific SPIN protocols, comparing them to other possible approaches and a theoretically optimal protocol. We find that the SPIN protocols can deliver 60% more data for a given amount of energy than conventional approaches. We also find that, in terms of dissemination rate and energy usage, the SPlN protocols perform close to the theoretical optimum.read more

A design and implementation of wireless sensor gateway for efficient querying and managing through World Wide Web
TL;DR: This paper presents the architecture of the sensor gateway for Web-based management and its implementation details, and assumes that wireless sensor networks have 3-level regional hierarchy, but the gateway is flexible enough to cooperate with other type sensor networks.

Analysis of wired short cuts in wireless sensor networks
Rohan Chitradurga,Ahmed Helmy +1 more
TL;DR: An analytical model is developed to analyze the gain in path length reduction by using short cuts in sensor networks and it is found that restricting the knowledge about the wires to 2 hops does not degrade the performance from the case when the authors have global knowledge of all wires.

TIBFIT: trust index based fault tolerance for arbitrary data faults in sensor networks
TL;DR: It is shown that once TIBFIT gathers enough system state, accurate event detection is possible even if more than 50% of the network nodes are compromised and its coverage evaluated with a varying number and varying intelligence of the malicious nodes.

Highly dynamic Destination-Sequenced Distance-Vector routing (DSDV) for mobile computers
TL;DR: The modifications address some of the previous objections to the use of Bellman-Ford, related to the poor looping properties of such algorithms in the face of broken links and the resulting time dependent nature of the interconnection topology describing the links between the Mobile hosts.

Multicast routing in datagram internetworks and extended LANs
TL;DR: In this paper, the authors specify extensions to two common internetwork routing algorithms (distancevector routing and link-state routing) to support low-delay datagram multicasting beyond a single LAN, and discuss how the use of multicast scope control and hierarchical multicast routing allows the multicast service to scale up to large internetworks.
